Hello sir, when I open the browser, it shows like this : {"message":"Cannot read property 'aggregate' of undefined"}. why?

body parser is now part of express, no need to import it separately afaik.. great node js tutorial.

[anthonygayflor]

Awesome tutorial. Really cleared things up for me.

This tutorial helped me and taught me a lot. I made my own application with multiple collections. So my question is how do I use autocomplete to display data from multiple collections, not just one collection. What should I do?

[ivankraev]

Is there a way to create search index programatically ?

[oanagiorgi]

Hi! How am I supposed to display data from the collection if I have string fields(like "recipe_type": String)? Shall I still use append, but without forEach? Thanks, very useful tutorial :)

Sir what is the limit to set on results returned by the query, suppose if a query matches with 100 documents or more than 100 then it will be worse for the user and also for the page. can we make it like google based searches which only show only 10 results on the basis of high relevance scores based?

this has been great but I can;'t seem to get the data I need lol just keeps returning an empty array.. maybe it's the format of my DB..

How performant is this? Let's say you have over 10.000 users calling the backend on every search.
